fix(ci): add workaround for Parcel not working with Yarn PnP

[wojtekmaj]

What's the problem this PR addresses?

It seems like the issue (https://github.com/parcel-bundler/parcel/issues/9114) is stuck on Parcel's side with no interest of it being fixed.

How did you fix it?

While this is not ideal, that leaves us with two choices: add a workaround and continue testing Parcel, or remove E2E tests for Parcel altogether. I chose the former.
